Stepping into 2021, the Indian Space Research Organisation (ISRO) has chalked out its decadal plan which includes development of a heavy-lift rocket, reusable satellite launch vehicle, semi-cryogenic engine, among other progressions in satellite technology, said a top official.

In the short term, the space agency has to realise the first developmental flight of the Small Satellite Launch Vehicle (SSLV) operational Geo-Imaging capability, the third moon mission Chandrayaan-3, the first solar mission Aditya-L1, and the first Indian Data Relay Satellite.

"The first unmanned flight under the Gaganyaan Programme is another significant milestone to be achieved this year," ISRO Chairman K. Sivan, who is also Secretary, Department of Space, ISRO said.

Sivan said: "In this decade, the VSSC (Vikram Sarabhai Space Centre), the lead centre for space transportation systems, will carry forward its competence in launch vehicle development towards heavy lift capabilities, achieving partial & full reusability and achieving progress in scramjet engine research."

According to Sivan, the Liquid Propulsion Systems Centre (LPSC) will fructify the much-awaited high thrust semi-cryogenic propulsion capability, which is expected to boost the lifting capability of Indian rockets to Geostationary Transfer Orbit (GTO) to almost 5.5 ton while also focusing on liquid oxygen (oxidiser)-Methane propulsion, green propulsion as well as electric propulsion.

He also said ISRO Propulsion Complex (IPRC) needs to gear up its test facilities to support the qualification of the new propulsion systems and also expand its integration facilities to realise the new semi-cryogenic and LOX/Methane engines.

"In the next decade, emphasis will be on satellite constellation for broadband communication, all electric satellite platform and high performance satellite platforms in all the application areas," Sivan said as regards the decadal plans for the U.R. Rao Satellite Centre (URSC).
